So, of course, I did it again last week.
My campers ranged in age from 3 to 13 years. There were over 45 campers, divided into 5 groups. Group 4, the 12 boys, were a riot. The challenge for me is to discover what kind of crafts are not unreasonable in expense, work in the timeframe, hopefully dry by 1 p.m., and can be made doable for preschoolers and highschoolers; boys and girls.
For Day 1 (and Day 4!) I took a page from Earthgirl's 6th birthday party, a 70s shendig, and brought a spool of leather thong rope and a big container of pony beads. Simplicity itself!
They were a hit with girls and boys.
